Today’s guest post comes from Catherine B. Chan and Rhonda C. Bell, Professors in Human Nutrition at the University of Alberta. It describes their Pure Prairie Eating Plan (PPEP) and how they went about developing this rather unique venture into eating local.
Healthy eating is a key factor in preventing and treating chronic diseases such as heart disease, stroke, cancer and diabetes. According to the World Health Organization, good nutrition is one of 4 key factors that could help postpone or avoid 90% of type 2 diabetes and 80% of coronary heart disease.
The Mediterranean Diet has gained popularity as a healthy diet, but evidence gathered through research on Canadian prairiegrown products (canola, flax, barley, pulses, dairy and meats) demonstrates that many local foods have similar nutritional qualities and would be more acceptable and accessible to people who live in Alberta, Saskatchewan and Manitoba.
Our recent project was conceived to develop, test and demonstrate the potential health benefits of a dietary pattern based on foods that are commonly grown and consumed in a “made in Canada” menu plan.
How the Pure Prairie Eating Plan (PPEP) was developed
The original purpose of the menu plan was to help people with type 2 diabetes adhere to the nutrition recommendations of the Canadian Diabetes Association (CDA) by focusing on healthy food choices with a local flavour. The menu plan concept integrates knowledge gained through research related to consumer behavior, behavior change, and nutritional quality of dairy, meats,
canola, pulses and grains.
During its development, it was recognized that a diet healthy for people with diabetes is a diet healthy for everyone. This notion was reinforced in a Consensus Conference with people living with type 2 diabetes, who felt strongly that their diet should not be different from others.
This approach provided knowledge that formed the basis of a 4-week menu plan focused on foods that are grown and readily available in the Canadian prairies. The plan consists of 28 days of diabetes-friendly menus including 3 meals and 3 snacks each day, approximately 100 recipes, tips for healthy eating, pantry and grocery lists and other helpful information.
If followed consistently, the menus meet the recommendations of Eating Well with Canada’s Food Guide on a daily basis, and over 1 week averages approximately 2000 kcal/day with macronutrient distribution consistent with health recommendations.
The menus also provide total fibre between 25 and 50 g/day. Many of the recipes have been obtained from our provincial agricultural commodity groups (see http://pureprairie.ca/oursponsors/).
The recipe ingredients feature many homegrown foods from each food group. They are quick and easy to make…and tasty!
Our Research Findings
Funding was secured through the Alberta Diabetes Institute to pilot test the menu plan concept in a 12-week intervention that measured both quantitative (disease biomarkers) and qualitative (acceptability, accessibility and acceptability) responses to the menu plan of 15 people with type 2 diabetes.
The results, published in the Canadian Journal of Diabetes, showed that most participants liked the menu plan and their A1c decreased by an average of 1%.
However, many were not used to cooking from scratch and cited time as a barrier to using the menu plan more. The benefits of the menu plan included more structure in participants’ diets, increased frequency of snacking, increased awareness of food choices, purchasing healthier foods and better portion control.
Participants were aware of better blood sugar control. Participants were pleased with the variety of food choices and liked the taste of the recipes. They also liked the flexibility of the menu plan.
In the second phase, which included 73 participants, we included a 5-week curriculum delivered in a smallgroup setting with a facilitator and included assessment of hemoglobin A1c as a measure of blood sugar control as well as cardiovascular risk factors. Nutrient intake was assessed using a computerbased 24-hour recall system called WebSpan.
In this study, 86% of those enrolled completed all aspects of the programme, including the 3-month followup. On average, there were decreases in A1c (0.7%), body mass index (0.6 kg/m2) and waist circumference (2 cm). (Note that a decrease in A1c of 0.5% is considered to be a clinically relevant improvement in blood sugar control.)
Although the weight loss was relatively small, it correlated with the reduction in A1c more strongly than any other factor examined.
Analysis of nutrient intakes showed decreases in total energy intake (127 kcal/day), total fat (7 g), total sugar (25 g) and sodium (469 mg).
The Pure Prairie Eating Plan (PPEP)
With promising outcomes regarding the nutritional adequacy and acceptability of the menu plan, and with encouragement from Alberta agricultural commodity groups and others, we packaged and rebranded the menu plan as the Pure Prairie Eating Plan (PPEP): Fresh Food, Practical Menus and a Healthy Lifestyle.
PPEP is available for purchase in selected bookstores throughout the prairies and proceeds from its sale will be used to further research into improving the lifestyle behaviours of Canadians with or at risk of chronic diseases.

If you were trying to build a coordinated provincial strategy to promote healthy weight in children and youth, where would you start? This has been a question on the minds of a team of healthcare providers and researchers in Manitoba for some time now.
Manitoba has the highest rate of type 2 diabetes in children in Canada, a condition that is in part related to obesity. In Manitoba, youth are diagnosed with type 2 diabetes at a rate 20 times higher than in any other province.
There are well-established, multidisciplinary clinical programs in our province that work with youth living with type 2 diabetes. For example, the Diabetes Education Resource for Children and Adolescents, which has existed since 1985, runs two weekly clinics and an outreach program for youth affected by type 2 diabetes.
Recently, the diabetes care team joined forces with pediatric kidney specialists in the province to provide a combined clinic for youth affected by both type 2 diabetes and kidney complications.
Manitoba is also home to the Maestro Project, which helps teens living with type 2 diabetes navigate what could otherwise be a difficult transition from pediatric to adult health care services and teams.
Similarly, research teams that include community advisors and families are tackling important questions related to the origins of type 2 diabetes and exploring innovative interventions to improve the health and quality of life for kids with this diagnosis.
Members of the DREAM (Diabetes Research Envisioned and Accomplished in Manitoba) Theme at the Children’s Hospital Research Institute of Manitoba are studying important biological, social and psychological factors linked with early kidney disease in youth with type 2 diabetes in a study called iCARE (Improving renal Complications in Adolescents with type 2 diabetes through REsearch).
While we have made significant progress in the area of type 2 diabetes care and research, we have made less progress in the areas of prevention and treatment of obesity in children and youth. We are one of the few provinces in Canada without a specialized clinical team dedicated to pediatric obesity. We lack a comprehensive provincial strategy that can link health care providers to each other, or to existing community programs that might help families. Gaps in services can leave families without access to care that could help their children. This is the issue that we have decided to tackle in a study that was recently funded by the Children’s Hospital Research Institute of Manitoba.
Our study is called “Mapping the state of pediatric weight management programs in Manitoba.” We will start with a survey within Manitoba, to identify existing programs that are available to families affected by obesity in our province. We want to know what is currently available. Where can health care providers refer families? And importantly, what resources are missing in our province to be able to provide an evidence-based approach to pediatric weight management?
While the title suggests we are solely focused on Manitoba, we are in fact looking to shape our provinces’ approach by learning from others across Canada and the United States.
To do this, the second part of the study will involve updating a 2010 study that mapped Canadian pediatric weight management programs to understand what has changed on the national landscape. What new programs exist and where? What programs are no longer offered and why?
Then we will move on to more in-depth conversations with members of the eight clinics involved in the Canadian Pediatric Weight Management Registry (CANPWR), and an additional eight clinics in the United States to better understand how their approaches evolved, barriers and successes that they have experienced and other key learnings that they can share to help inform a Manitoba approach.
Once we have brought the information from these activities together, we will hold a meeting for families, community members, clinicians, researchers, healthy living organizations and policy makers in the province. We will look at the data together and prioritize the next important steps on this journey.
We all need to work together to build healthier families, healthier communities and healthier populations. This novel approach that integrates the experiences and priorities of others will ensure that when we launch a new direction for pediatric obesity management in Manitoba, it will be relevant and targeted to everyone’s needs.

The recently released Canadian Practice Guidelines on the prevention and management of overweight and obesity in children and youth released by the Canadian Task Force on Preventive Health Care (CMAJ 2015), rightly recommended that surgery not be routinely offered to children or youth who are overweight or obese.
Nevertheless, there is increasing evidence that some of these kids, especially those with severe obesity, may well require rather drastic treatments that go well beyond the current clinical practice of doing almost nothing.
Just how ill kids can be before they are generally considered potential candidates for bariatric surgery is evident from a study by Marc Michalsky and colleagues, who just published the baseline characteristics of participants in the Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) Study, a prospective cohort study following patients undergoing bariatric surgery at five adolescent weight-loss surgery centers in the United States (JAMA Pediatrics).
While the mean age of participants was 17 with a median body mass index of 50, the prevalence of cardiovascular risk factors was remarkable: fasting hyperinsulinemia (74%), elevated hsCRP (75%), dyslipidemia (50%), elevated blood pressure (49%), impaired fasting glucose levels (26%), and diabetes mellitus (14%).
Not reported in this paper are the many non-cardiovascular problems raging from psychiatric issues to sleep apnea and muskuloskeletal problems, that often dramatically affect the life of these kids.
While surgery certainly appears rather drastic, the fact that these kids are undergoing surgery is merely an indicator of the fact that we don’t have effective medical treatments for this patient population, which would likely require a combination of behavioural interventions and polypharmacy to achieve anything close to the current weight-loss success of bariatric surgery.
That this cannot be the ultimate answer to obesity management (whether for kids or adults), is evident from the rising number of kids and adults presenting with ever-higher BMI’s and related comorbidity – not all of these can or will want surgery.
Thus, while current anti-obesity medications cannot compete with the magnitude of weight-loss generally seen with surgery, medications together with behavioural interventions may well play a role in helping prevent progressive weight gain in earlier stages of the disease.
Unfortunately, I am not aware of any studies that have explored the use of medications in kids to stabilize weight in order to avoid surgery. This would, in my opinion, be a very worthwhile use of such medications.
Last week at the 8th Annual Obesity Symposium hosted by the European Surgery Institute in Norderstedt, one of the case presentations included an individual with type 1 diabetes (no insulin production), who had gained weight and subsequently also developed increasing insulin resistance, the hallmark of type 2 diabetes.
In my discussion, I referred to this as 1+2 diabetes, or in other words, type 3 diabetes.
Unfortunately, it turns out that the term type 3 diabetes has already been proposed for the type of neuronal insulin resistance found in patients with Alzheimer’s disease.
As discussed in a paper by Suzanne de la Monte and Jack Wands published in the Journal of Diabetes Science and Technology,
“Referring to Alzheimer’s disease as Type 3 diabetes (T3DM) is justified, because the fundamental molecular and biochemical abnormalities overlap with T1DM and T2DM rather than mimic the effects of either one.”
These findings have considerable implications for our understanding of Alzheimer’s disease as a largely neuroendocrine disorder, which may in part be amenable to treatment with drugs normally used to treat type 1 and/or type 2 diabetes.
In retrospect, I believe, whoever came up with the term type 3 diabetes for Alzheimer’s disease, should perhaps have called it type 4 diabetes, given that the 1+2 diabetes is now increasingly common (and well studied) in patients with type 1 diabetes, who go on to develop type 2 diabetes (which, as discussed at the symposium responds quite well to bariatric or “metabolic” surgery).
